If you need to have an extra option for your CodeMirror Editor instance, you can use it this way:

editor.setOption("customTernData", {
  "a": {
    "foo": "bar-a",
    "bar": "baz-a"
  },
  "b": {
    "foo": "bar-b",
    "bar": "baz-b",
    "moo": "huzzah"
  }
})

And to access the data use the following snippet

editor.getOption("customTernData")

This way you can set and get the extra information you need to have it in the editor context itself and no need to store the information in the editor area.
